skin issues

Hello everyone. So I picked Marty up last thursday and things are going well. I do have a concern and I am not sure what to think about it. We already saw a vet and things are fine, however I noticed that she is constantly licking the area around her private area and also biting her legs. They don't look iritated. I meant to ask the vet about it but I forgot. any ideas as to what may be going on? Thank you.
